Stability: poor · Frequency: many
Weakly bonded old snow represents the main danger.
Weak layers in the upper part of the snowpack can be released over a wide area easily by individual winter sport participants. The avalanche prone locations are to be found in all aspects above approximately 2000 m. Such avalanche prone locations are numerous but are difficult to recognise. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Mostly avalanches are medium-sized. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Defensive route selection is recommended.
The old snowpack is faceted. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. The various wind slabs have bonded poorly with the old snowpack.
The avalanche danger will persist.
